Leaf Folder

 

1. The larvae fold the leaves, eat out the green tissue and produce white streaks. 2. The damage is highest during August-October. Spray the crop when the leaf damage reaches 10 per cent (ETL) with 350 ml of Hostathion 40 EC (triazophos) or 1 litre of Coroban/ Durmet/ Force 20 EC (chlorpyriphos) or 560 ml of Monocil 36 SL (monocrotophos) in 100 litres of water per acre.

Grasshoppers

 

1. Grasshoppers can damage rice at all stages of crop growth.

2. Both nymphs and adults feed on leaves by cutting the edges of leaves at all the growth stages of the rice crop.

3. Damage is found more on the margins of the field.

4. They sometimes cut the plants similar to cut worms.

5. When the grasshoppers are in greater numbers they can even feed on the midribs and total leaves and cause extensive defoliation.

Rice-ear-cutting-caterpillar

1. The larvae of this insect are gregarious in habit and are commonly known as ‘armyworm’. The young larvae feed on leaves, leaving only the mid-ribs and stems.

2. The old larvae cut off the panicles mostly at the base and hence the name “rice ear cutting caterpillar”. This stage of the insect causes serious loss to the paddy crop.

3. The larvae are shy of sunlight and generally feed at night. The damage to paddy crop is caused mostly during September to November.

4. The insect can be controlled by spraying the crop with 400 ml of Ekalux/Quinguard 25 EC (quinalphos) in 100 litres of water per acre.

5. As the pest is nocturnal in behavior, the spray should be done in evening hours for getting better results.

Rice Hispa

 

1. Rice hispa a serious pest in some areas of the Gurdaspur and Amritsar districts and is also found in the other rice growing areas of the state.

2. The grubs of this pest tunnel in to the leaves, whereas the adults are exposed feeders. The grubs cause damage by producing bold, white streaks on the leaves.

3. If the attack starts in the nursery, clip off and destroy the leaf tips of the affected seedlings before transplanting. 4. On the transplanted crop, spray 120 ml Methyl Parathion 50 EC (methyl parathion)/560 ml Monocil 36 SL (monocrotophos)/800 ml Ekalux 25 EC (quinalphos)/one litre Dursban 20 EC (chlorpyriphos) in 100 litres of water per acre with a manually operated sprayer. Repeat the spraying if the attack persists.

Plant hoppers

 

1. These hoppers include, whitebacked plant hopper and brown planthopper. Both nymphs and adults of these pests suck the cell sap particularly from the leaf-sheath from July to October. 2. The crop dries up in patches. As the plants dry up, the hoppers migrate to the adjoining plants and kill them. In a few days, the area of the dry patches enlarges. 3. About one month after transplanting, a few plants in the field should be slightly tilted and tapped 2 or 3 times at the base at weekly interval. 4. If minimum 5 plant hoppers per hill are seen floating in the water, only then the crop should be treated with insecticide. 5. The plant hoppers can be controlled by spraying 40 ml Confidor 200 SL (imidacloprid) or 800 ml Ekalux/Quinguard 25 EC (quinalphos) or one litre Coroban/Dursban 20 EC (chlorpyriphos) or 560 ml Thiodan/Endocel 35 EC (endosulfan) in 100 litres of water per acre. Repeat the spray if necessary. 6. For better effectiveness, direct the spray towards the base of the plants. If the damage is noticed at hopper burn stage, treat the affected spots along with their 3-4 metre periphery immediately as these spots harbour high population of the insect.

Rice stemborer

 

1. The larvae of these insects bore into the stem and cause damage from July to October.

2. The affected young plants show dead-hearts (yellowing and drying of central shoot) whereas the old ones produce empty earheads which turn white and stand erect.

3. The fields showing more than 5% dead hearts (economic threshold level) should be sprayed with 350 ml of Hostathion 40 EC (triazophos) or 560 ml of Monocil 36 SL (monocrotophos) or 1 litre of coroban / Dursban/ Lethal/ Chlorguard /Durmet / Classic/ Force 20 EC (chlorpyriphos) in 100 litres of water per acre.

4. Further application of any of these insecticides may be repeated as and when damage reaches economic threshold level.
